actually in 'default' when the black bar ties itself to the icons I get a faint dot. Ugly. Ironically not in Matte or GTK in their black bars. Or in transparency mode, anymore. Constant weirdness with plank this year.
I don't believe it's my background pic. I had dots last week, same pic, clearly with 3800 temp. This happened twice in XFCE, only one time I was able to solve it myself (change monitor refresh rate), the other time it was a known problem and an update took care of it.
I haven't experienced yet this weirdness in plank/endeavour (variation of the same budgie theme pack/dark blue background) so I brought that dock.theme
file to my budgie desktop and will compare it to the dock.theme
in solus tomorrow or when I have time down the road.
edit: added this for clarity "Or in transparency mode, anymore"
